3D printer material cooling device

Abstract

The invention discloses a material cooling device for a 3D printer, which includes a fixing frame, a printing nozzle is fixed at the bottom of the fixing frame, a printing nozzle is fixed at the bottom of the printing nozzle, and a cooling ring is installed on the printing nozzle. The bottom of the printing nozzle is located on both sides of the printing nozzle and a micro-fan is installed. An air guide cover is installed under the micro-fan. The air guide cover is provided with a shunt pipe connected to the cooling ring. The air guide cover The filter mechanism is installed inside. The invention installs a trumpet-shaped air guide cover under the fan, which improves the convergence ability and guiding of the cooling wind force, improves the cooling efficiency, and the filter foam can filter out impurities in the wind force, which solves the problem of impurities adhering to the model, metal The net plays the role of uniform airflow, which solves the problem of model deformation caused by excessive local wind force.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a material cooling device for 3D printers. Background technique [0002] 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. [0003] At present, the material cooling device installed on the nozzle of the 3D printer does not filter the exhausted air, which causes impurities to adhere to the surface of the high-temperature printed model, which affects the quality of the molding. A 3D printer material cooling device is proposed to solve the above existing problems. Contents of the invention [0004] The purpose of the present invention is to provide a 3D printer material cooling device to solve the problem in the prior art that the exhausted ...
